Radar Studies of the Ionosphere at Nonequatorial Latitudes

我们建议再继续三年的研究计划 目前由NSF Grant ATM-8721669支持。 大部分工作 将落入三个区域之一：（1）非相干散射 研究，特别是在高海拔地区，（2）极光雷达 （3）温带E区等离子体的研究 类似于赤道的不稳定性，也许 温带分布F. 一些努力也可能是 PMSE（Polar Mesospheric Summer Echoes，极地中层夏季回波） 在 在这些领域中的大多数， 正在进行中;在某些情况下，该计划已经存在了一些 多年来，它产生了巨大的科学回报。

We propose to continue for three more years the research program currently supported by NSF Grant ATM-8721669. Most of the work will fall into one of three areas: (1) incoherent scatter research, particularly at high altitudes, (2) auroral radar studies, and (3) studies of temperate latitude E-region plasma instabilities similar to those seen at the equator, and perhaps also temperate latitude spread F. Some effort may also be devoted to PMSE (polar mesospheric summer echoes) research. In most of these areas an active research program is already underway; in some cases the program has existed for a number of years and has produced a substantial scientific return.
